How to Calculate 90 days for CARB testing compliance
Navigating the Clean Truck Check: Understanding Your 90-Day Testing Window
The California Air Resources Board (CARB) is emphasizing the importance of timely emissions testing for heavy-duty vehicles, specifically reminding vehicle owners and testers about the critical 90-day testing window for the Clean Truck Check (CTC) program. To ensure your vehicle's emissions compliance test is successfully applied, it's crucial to understand how this window is calculated.
**What You Need to Know:**
* **Test Early, But Within the Window:** While CARB encourages vehicle owners to test as early as possible, this must be done within the 90-day window leading up to your specific testing deadline.
* **Accuracy is Key:** Any emissions compliance test submitted more than 90 days before your vehicle's deadline will **not** be accepted. This means the test will be invalid, and you'll be required to re-test your vehicle within the correct 90-day period.
* **CTC-VIS is Your Guide:** Your 90-day window is determined by the specific testing deadline shown in your vehicle's CTC-VIS account. Do not assume the 90-day window is simply three calendar months, as this can lead to inaccuracies.
* **Testers' Recommendation:** While testers are not responsible for determining if a vehicle is within its 90-day window, CARB recommends that testers confirm the CTC-VIS test due date with the vehicle owner before scheduling a test. This proactive step can help prevent re-testing and ensure a smooth process for everyone involved.
**Helpful Resource:**

By understanding and adhering to these guidelines, vehicle owners can ensure their compliance tests are valid, avoiding unnecessary re-testing and penalties. Always refer to your CTC-VIS account for the most accurate information regarding your vehicle's testing deadline.
